Here are some of Triton Showers Support Teams most frequently asked questions.
I am replacing an old manual mixer valve and the hot supply to it is on the right. The new Triton bar mixer shower I am fitting has the hot connection on the left. Can I connect the hot supply to the cold inlet and change something on the mixer valve to suite?
There is no provision on a bar mixer shower to alter the thermostatic cartridge inside and have hot water entering the cold-water inlet. It will be necessary to alter the pipe arrangements and have the hot water supply on the left.
Do I need to use a cylinder flange when installing a Triton mixer or power shower?
It is not necessary to use a cylinder flange when installing our mixer and pump products. Teeing into the inclined section of pipe from the top of the cylinder is the preferred method of connection.
Providing the tee is pointing down, air released from the heated water in the cylinder will bypass the tee and escape out of the expansion pipe.
If it is not possible to fit the tee in this fashion it can be installed in the falling supply to other outlets, providing it is below the expansion pipe tee and is the first take off point before other taps.
Do you make a mixer shower that I can install onto a gravity hot water supply and mains cold water supply?
We do not recommend installing our mixer showers onto unbalanced supplies of this type. While most of our mixer showers incorporate a single check valve in each inlet there is always a risk that debris may enter the mixer and prevent the check valve in the hot inlet from sealing off. Should this occur mains water at pressure will flow into the hot supply forcing water in the cylinder back into the cold water cistern potentially causing water to overflow from the cistern and damaging property.
Does Triton have a range of mixer showers with tamper proof controls?
Triton’s Elina range of mixer showers has tamper proof controls. A tool to remove the controls is supplied with the valve.
How can I determine the pressure and flow I will get from a Triton mixer shower connected to gravity supplies?
The principle is that for every 1 meter head of water, (as measured from the base of the cold water cistern to the top of the showerhead) there will be a pressure into the mixer of 0.1 bar. This is a theoretical pressure as restrictions within pipe fittings and the shower mixer valve will reduce the pressure to a degree.
Providing only minimal restrictions are present in the supplies and terminal fitting the additional measurement (height) of water within the cistern will usually compensate for pressure losses in the supplies.
Where flow-rate is quoted for mixer valves at 0.1 bar this is an open outlet figure i.e. flow of water from the mixer outlet without the shower hose and showerhead fitted.
How do I find out what flow rate I will get from a Triton mixer shower before purchasing?
Firstly you will need to establish whether the mixer shower you are interested in is suitable for the water system in the property i.e. a low – pressure or high-pressure system.
By accessing the fitting instructions for the product you will be able to establish the flow rate from a graph detailing the open outlet flow rate at various pressures i.e. flow that will be available from the mixer outlet without the showerhead connected.
Alternatively you can contact our customer service team on 0870 067 3333 who will be happy to provide the information you require.
How many mixer showers can be fed from a Thermal Store hot water system?
The output from a thermal store unit depends on its size (stored volume), heat transfer capability and the water pressure entering the unit. Some are only capable of delivering sufficient hot water to one mixer shower whereas others can supply 3 or 4 showers simultaneously. Always check the specification of the thermal store before selecting any mixer shower to ensure that the capacity of the heating appliance is compatible with the shower and required usage.
I want to install a mixer shower in a loft conversion where the cold water cistern is lower than the showerhead. Which product do you recommend?
The easiest product to install would be the Satellites Sirona with LP mixing unit and Metis shower kit . The mixer unit can be installed just below the cold water cistern. Pumps in the mixer unit will deliver water at pressure to the showering area located above.
Is your pressure compensating mixer shower compatible with a thermal store hot water system?
The pressure-compensating valve is compatible with this type of high pressure system. This shower is designed to maintain the set showering temperature when a pressure change occurs in either the hot or cold supply i.e. when another tap is turned on in the property. However this type of mixer shower does not respond to any changes that occur in the hot water supply temperature.
Providing the thermal store unit is capable of maintaining a constant water temperature when other taps are operated, then the pressure-compensating valve can maintain comfortable showering temperature. Where there are noticeable fluctuations in domestic hot water temperature then a thermostatic mixer valve should be specified.
What do I need to check most when selecting a replacement for my existing mixer shower?
Check that the mixer shower you select is compatible with your water system i.e. low or high pressure.
Check that the mixer you select is thermostatic in operation if you want optimum temperature control.
Check that the inlet fittings on the new mixer offer the same measurement between them as the existing mixer, if not it will usually be necessary to alter pipework to suit.
Check that the existing hot and cold supply will connect to the correct inlets on the new mixer i.e. hot on the left and cold on the right, if not it will be necessary to alter the pipework to suit.
What do I need to check most when selecting and installing a built in mixer shower?
Check that the wall structure can accommodate the routing of water pipes and the building in depth of the selected mixer.
Check that hot and cold supplies enter the correct inlets on the mixer before making good the wall.
Ensure when plastering and tiling around the mixer shower that filters and check valves are accessible for future maintenance
What size cold water cistern and hot water cylinder do I need to supply a low-pressure mixer shower?
The minimum size cold water tank (cistern) we recommend for one shower unit is 115 liters’ (25 gallons). Hot water storage will depend on a number of factors such as, time in the shower, flow rate of the shower and the stored water temperature and recovery time of the hot water cylinder. As a rule of thumb a low-pressure mixer shower will deliver a flow rate of 5l/m and will use around 3 liters’ of hot water a minute. Therefore, this will use up the contents of a domestic hot water storage cylinder containing 117 litters of which 93 litters is useable, in approximately 30 minutes.
If a booster pump is fitted to improve shower performance then the hot water used can be in the region of 12 l/m, which means showering time will be reduced to approximately 8 minutes
The larger the hot water cylinder the better.
When installing a thermostatic mixer shower in a care home, are there any special requirements I should be aware of for this type of situation?
Care homes generally follow NHSE guidance on the delivery of safe hot water temperature to outlets. Fitting a TMV3 mixer valve shower will fully meet the requirements for the delivery of safe water temperature in this type of establishment.
In addition to the shower, appliances such as basins, bidets and baths will also require TMV3 thermostatic control on the hot water outlets.
